Sample Color
The Sample Color module provides a way to compare a specific image area with known colors to determine which
color is most representative of the area. The module performs an averaging over the specified image area
and compares this resulting value with color values entered into the Nearest Color list. Successive modules
can then access the results of this module via variables to trigger actions based on the results
of this module.

buttons.
3. Add Custom - Add a custom color to the list
4. Add Current - Add the current intensity to the list
5. Add Variable - Add a variable that contains a color to compare to
6. Del/Del All - Delete a or all the selected colors in the list.
